The structural method of fault location in a LAN segment has been proposed. It combines a method of many-valued fault table's analysis using vectors of elementary probes with a method of structural fault location by reachability matrix, where lines of matrix are used instead of fault table lines. Such approach allows to reduce an area of suspected faults… (More)
An approach to LAN model creation with regard to problems of digital device technical diagnosis is proposed. The problems discussed include model analysis (fault simulation), test generation and defect search. Program implementation of models and procedures in the VHDL language and use of CAD active-HDL have confirmed the efficiency of the models.
The method of response time optimization in LANs based on planning of active experiment is suggested. The network faults (implicit faults and bottlenecks) exert the most considerable influence on response time of server on to client's query. The proposed procedure of considered fault s location allows to decrease labouriousness, reduce time costs and… (More)
The processes of RTCP data transmission in videoconference applications with the centralized architecture are considered and the problems related with these processes are formulated. The involving of diagnostic node (DN) is proposed for solving the problem of RTCP broadcast traffic reducing.
